==Differentiating Pulseless electrical activity from Other Diseases==
 
==Overview==
PEA(Pulseless electrical activity) should be differentiated from [[asystole]] and [[ventricular fibrillation]], [[Ventricular flutter]], [[Torsade de Pointes]], [[Asystole]] etc.
 
==Differentiating Pulseless Electrical Activity from Other Diseases==
*[[Asystole]]: In [[asystole]], there is cessation of any cardiac activity and lack of cardiac output on this basis.  In PEA, electrical activity is present.
*[[Asystole]]: In [[asystole]], there is cessation of any cardiac activity and lack of cardiac output on this basis.  In PEA, electrical activity is present.
*[[Ventricular fibrillation]]: There is no organized electrical activity present.  There are only fine fibrillatory waves present in ventricular fibrillation. In PEA, there is organized electrical activity.
*[[Ventricular fibrillation]]: There is no organized electrical activity present.  There are only fine fibrillatory waves present in ventricular fibrillation. In PEA, there is organized electrical activity.
*[[Peripheral arterial disease]]: The inability to feel a peripheral pulse may be due to severe [[peripheral arterial disease]].
*[[Peripheral arterial disease]]: The inability to feel a peripheral pulse may be due to severe [[peripheral arterial disease]].

Overview

PEA(Pulseless electrical activity) should be differentiated from asystole and ventricular fibrillation, Ventricular flutter, Torsade de Pointes, Asystole etc.

Differentiating Pulseless Electrical Activity from Other Diseases

The table below provides information on the differential diagnosis of pulseless electrical activity in terms of ECG appearance:

Disease Name Causes ECG Characteristics ECG view
Ventricular tachycardia [1][2][3][4][5]
[6]
Ventricular fibrillation [7][8][9][10]
[11]
Ventricular flutter [12][13][14]
[15]
Asystole [16][17]
  • There is no electrical activity in the asystole
[18]
Pulseless electrical activity [19][20][21][22]
[23]
Torsade de Pointes [24][25][26]
  1. Paroxysms of VT with irregular RR intervals.
  2. A ventricular rate between 200 and 250 beats per minute.
  3. Two or more cycles of QRS complexes with alternating polarity.
  4. Changing amplitude of the QRS complexes in each cycle in a sinusoidal fashion.
  5. Prolongation of the QT interval.
  6. Is often initiated by a PVC with a long coupling interval, R on T phenomenon.
  7. There are usually 5 to 20 complexes in each cycle.
